Abstract

A cooling tower is a heat exchanger equipment that uses water splashing media to lower the temperature by extracting heat from the water and emitting it into the atmosphere. Wind speed or velocity of wind waves is a fundamental atmospheric quantity caused by moving air from high pressure to low pressure while wind is moving air. Air velocity has an effect on the value of heat transfer coefficient, the faster the air, the better the value so that the heat transfer that occurs is also better. Research was also carried out on the human body to see forced convection due to the movement of these parts of the body, resulting in that the faster the body moves, the better the heat transfer coefficient value, this is related to the air flow that occurs on the body surface. The test shows that the more blower rotation make faster the heat transfer that occurs. At 2500 RPM rotation shows higher heat transfer by producing an average of 29.210 watts, the displacement decreases when the rotation is lowered to 1700 RPM to produce an average of 20.677 watts. The effectiveness of the tool by increasing the rotation from 1700 to 2500 by 32%
